WHAT THE TEST MEASURES

About This Assessment

Medication Adherence Assessment Questionnaire (MAS-12) Test

compliance

This questionnaire is a brief self-report tool used to screen for barriers to taking prescribed medications as directed. The Medication Adherence Assessment Questionnaire (MAS-12) is intended to support clinical conversations about adherence-related behaviors and common obstacles (e.g., forgetfulness, doubts about benefit, or practical difficulties).

It consists of 10 items and typically takes about 2 minutes to complete. Responses may help identify areas where additional education, problem-solving, or regimen support is needed and can be used to inform follow-up assessment or care planning.

In clinical or outpatient settings, the Medication Adherence Assessment Questionnaire (MAS-12) may be administered as part of routine monitoring to flag potential nonadherence and guide targeted intervention.
